( Department of Environmental Science and Engineering, Hunan University, Changsha 410082, China ) Abstract: In order to investigate the feasibility of electrokinetic soil processing on the removal of Cd from Cd-contaminated red soils, a laboratory experiment was conducted. A constant direct current density of 0.5 mA/cm2 was applied. The result shows that the Cd-removal efficiency was remarkably pH-dependent, which is caused by the change of Cd retention capacity of the red soils under different pH conditions. The initial Cd concentration was1 490 mg/kg and over 79 % of it was removed from the red soils after 96 hours’ treatment. The energy expenditure per unit volume at the end of experiment was about 77.6 kW.h/m3 and the capital consumed by the whole experiment was 42.6 RMB Yuan/m3, which suggest that electrokinetic soil processing is a promising technology for remedying cd-contaminated red soils due to its high removal efficiency and low energy consumption. Key words: cadmium; electrokinetic soil processing; red soil; pH; electroosmosis TNMSC |
